Natural Causes:
* Old Age: Squirrels have a relatively short lifespan, typically 2-5 years in the wild. Some may live longer, but their bodies naturally weaken with age.
* Disease: Squirrels are susceptible to various diseases, including rabies, distemper, and parasites.
* Predation: Many animals prey on squirrels, including hawks, owls, snakes, coyotes, foxes, and domestic cats.
* Starvation: Squirrels can die from lack of food during harsh winters or if their food sources become scarce.
* Accidents: Squirrels can fall from trees, be struck by cars, or drown in water sources.
Human-Related Causes:
* Habitat Loss: Deforestation and urbanization destroy squirrel habitats, making it harder for them to find food and shelter.
* Pesticides: Pesticides used in gardens and lawns can harm squirrels, leading to poisoning.
* Vehicle Collisions: Squirrels are often killed by cars, especially when crossing roads.
* Trapping: Squirrels are sometimes trapped by humans for pest control or to prevent damage to crops.
Other Causes:
* Climate Change: Climate change can disrupt squirrel populations by altering their food sources and habitats.
* Competition: Squirrels compete with each other for resources, and this competition can lead to death, especially during times of food scarcity.
It's important to remember that squirrels are wild animals and are subject to the natural forces of their environment. We can play a role in their survival by providing them with safe habitats, reducing our use of pesticides, and being mindful of their presence when driving.
